4 Claims.

This invention relates to a device for installing a ventilating screenof the roll type inconjunction with window frames and analogousstructures providing light and ventilation.

The principal object of the invention is the provision of a novel devicewith which a screen of the indicated character may be readily installedand removed; which retains the screen material taut and smooth spanningthe window opening;

which makes it possible to wind the screen material so as to be clear ofa desired portion of the window opening whenever it is necessary ordesirable.

The invention co nsists in the novel arrangement and combination of thevarious parts,'as

well as the details The nature of the ing features and a ofconstruction. invention and its distinguishdvantages will appear whenthe following specification is read in connection with the accompanyingdrawings, in which:

n taken on the line 99 of Referring now more particularly to the severalviews of the drawings, it will be apparent that the device of thepresent invention includes a supporting and guiding structure adapted tobe arranged in a window frame, and which supports and encloses a springroller for the screen material, and which guides the screen material asit is wound on and unwound from the roller. The said structure includesa base or sill bar I0, connecting guide tubes II, and a housing orcasing terial is arranged.

hollow construction and I2 within which the roller for the screen ma-Each of the tubes II is of has a slot I3 extendin longitudinally thereofand which terminates short of the lower end, an

d which is widened and opens through the upper end as at I4 for apurpose to appear. The tubes I I are disposed vertically in spacedparallel relation between the bar It] and the housing I2. tubes II isconnected The lower end of each of the with the bar III by an adjustingscrew I5 which is swivelly connected with the bar ID as at I6. The screwI5 has a plurality of radially disposedholes II therein to receive asuitable instrument A bracket bearing I8, 4, is mounted on the the screwI5 to adjust for the purpose of turning the tube II up and down. shownmost clearly in Fig. upper end of each of the tubes II. To accomplishthis, the bearing I8 has a depending. portion I9 which fits into thetube, the latter having a notch to receive a laterally extending pin 2I.on

the portion I9 to prevent the bearing I8 from turning with respect tothe tube. The portion I 9 has a groove 22 therein complemental to the,slot I3 in the tube. It will be obvious that each of the bearings 18 isdetachably connected with the upper end of the related tube II. by thebearings I8.

The housing I2 is removably supported The housing I2 is constructedpreferably of heavy sheet metal and comprises two sections, a section 23and a section 24. Each end of the housing section 23 has a depression orrecess 25. and a slot 26. Each end of the housing section 24 has anmtegral portion 21 resiliency springs.

whose upper end has a flange 28. Due to the of the metal the portions 21serve as The portions 21 are receivable and fit within the depressions25 respectively, and the flanges 28 are engageable and fit in the slots26 respectively in the housing section 23. Thus the housing section 24may be with or secured to the housing section 23. The housing section 24is narrower than the section 23 to close a portion of the bottom of thesection 23 and also to leave an opening extending longitudinally of thehousing at the back thereof through which the screen material is woundand unwound. The housing section 24 has a longitudinal reinforcingflange 29 which abuts the frontwall of the hou each of the bearings singsection 23. If desired 28 may be provided with a depending bracket 30for the purpose of supporting the roller of In order to accommodate thethe bearings I8, the

opening 3| therein. The housing I2 is mounted on or supported by thebearings I8 which are disan ordinary window shade. bracket on each ofhousing section 24 hasan posed within the same.

The bearings I8 constitute means for supporting a spring and ratchetroller construction including trunnions which are re- 32 of any suitabledetachably associated ceived in holes 33 in the bearings l8respectively. A piece oi. screen material 34 of suitable size to spanthe distance between the tubes II and to reach from the roller 32 to thebar I 0 is provided. The upper end of the material 34 issecured to theroller 32 in any practical manner, and the opposite side edges of thematerial 34 extend or pro ject into the slots l3 of the rods IIrespectively, as the material 34 is wound on and unwound from the roller32, the walls of said slots l3 constituting guiding means for thematerial. The lower end of the material 34 is bent in connection with alongitudinally bent strip 35 having a forwar'dly projecting flange 36throughout the length thereof. Another strip 31 approximately equal inlength to the strip 35 is laid against the bent end of the material 34.Suitable fastening elements 38 are employed to fasten the strips 35 and31 together in binding engagement with the material 34. Each of thestrips 35 and 31 at the opposite ends thereof is notched as at 39 toclear the unslotted lower end portion of the tube ll, so that the flange36 may be brought down into contact with the bar l0. Suitable latches 40are secured to the strip 31. Each of the latches has spring pressedlatch members 4| which are releasably engageable with a headed stud 42secured to the bar H1. The flange 36 has openings 43 therein toaccommodate the studs 42. A suitable handle 44 is secured to the strip31 intermediate the ends thereof for the purpose of winding andunwinding the material 34. The latches 40 will automatically engage thestuds 42 when the material 34 is unwound sufficiently so that thematerial 34 will entirely close the opening of the window frame 45. Thelatches 40 must be manually released to wind the material 34 on theroller 32.

the material 34 to wind on the roller, subject to the action of theratchet of the roller which will retain the material 34 extended in suchmanner as to be clear of any desired portion of the window openingwhenever it is necessary or desirable.

The various elements will be so proportioned as to apply the screen to awindow frame of known It will be understood that thereaction of thespring of the roller 32 will cause caused to enter the slots l3 if forany reason the opposite side edges should leave the slots.
